GENERAL DESCRIPTION
The ADuM6020/ADuM60281 are isoPower®, integrated, isolated
dc-to-dc converters. Based on the Analog Devices, Inc., iCoupler®
technology, these dc-to-dc converters provide regulated, isolated
power that is below CISPR22 Class B limits at full load on a
2‑layer printed circuit board (PCB) with ferrites. Common voltage
combinations and the associated current output levels are shown in
Table 1 through Table 4.
input to 3.3 V output operations, use the ADuM6020-3BRIZ and
the ADuM6028-3BRIZ. See the Pin Configuration and Function
Descriptions section and the Ordering Guide for more information.
The ADuM6020/ADuM6028 eliminate the need to design and build
isolated dc-to-dc converters in applications up to 500 mW. The
iCoupler chip scale transformer technology is used for the magnetic
components of the dc-to-dc converter. The result is a small form
factor, isolated solution.
The ADuM6020/ADuM6028 isolated dc-to-dc converters provide
two different package variants: the ADuM6020 in a wide-body,
16-lead SOIC_IC package, and the ADuM6028 in the space-saving,
8-lead, wide-body SOIC_IC package. For 5 V input operations,
use the ADuM6020-5BRIZ and the ADuM6028-5BRIZ. For 3.3 V

THEORY OF OPERATION
The ADuM6020/ADuM6028 dc-to-dc converters work on principles
that are common to most standard power supplies. The converters
have a split controller architecture with isolated PWM feedback.
VDDP power is supplied to an oscillating circuit that switches current
into a chip scale air core transformer. Power transferred to the secondary side is rectified and regulated to 3.3 V or 5.0 V, depending
on the setting of the VSEL pin. Note that the ADuM6020-3BRIZ
and the ADuM6028-3BRIZ can only be used for 3.3 V input to
3.3 V output applications, and the ADuM6020-5BRIZ and the ADuM6028-5BRIZ operate best for 5 V input applications. The secondary (VISO) side controller regulates the output by creating a PWM
control signal that is sent to the primary (VDDP) side by a dedicated
iCoupler data channel. The PWM modulates the oscillator circuit
to control the power being sent to the secondary side. Feedback
allows significantly higher power and efficiency.
The ADuM6020/ADuM6028 implement undervoltage lockout (UVLO) with hysteresis on the primary and secondary side input and
output pins. The UVLO feature ensures that the converters do not
go into oscillation due to noisy input power or slow power-on ramp
rates.

APPLICATIONS INFORMATION
PCB LAYOUT
The ADuM6020/ADuM6028 isoPower integrated dc-to-dc converters require power supply bypassing at the input and output supply
pins (see Figure 21 and Figure 22). Low effective series resistance
(ESR) 0.1 µF bypass capacitors are required between the VDDP pin
and GND1 pin, as close to the chip pads as possible. Low ESR
0.1 µF or 0.22 µF capacitors are required between the VISO pin
and GNDISO pin, as close to the chip pads as possible (see the
CISO note in Figure 23 and Figure 24 for more information). The
isoPower inputs require multiple passive components to bypass the
power effectively, as well as set the output voltage and bypass the
core voltage regulator (see Figure 21 through Figure 26).
is required. The recommended capacitor values are 0.1 µF and
10 µF for VDDP. The smaller capacitor must have a low ESR. For
example, use of a ceramic capacitor is advised. The total lead
length between the ends of the 0.1 μF low ESR capacitors, and the
power supply pins must not exceed 2 mm.
To reduce the level of electromagnetic radiation, the impedance to
high frequency currents between the VISO and GNDISO pins and
the PCB trace connections can be increased. Using this method
of electromagnetic interference (EMI) suppression controls the radiating signal at its source by placing surface-mount ferrite beads in
series with the VISO and GNDISO pins, as shown in Figure 25 and
Figure 26. The impedance of the ferrite bead is chosen to be about
1.8 kΩ between the 100 MHz and 1 GHz frequency range to reduce
the emissions at the 180 MHz primary switching frequency and the
360 MHz secondary side rectifying frequency and harmonics. See
Table 20 for examples of appropriate surface-mount ferrite beads.

The power supply section of the ADuM6020/ADuM6028 uses a 180
MHz oscillator frequency to efficiently pass power through its chip
scale transformers. Bypass capacitors are required for several operating frequencies. Noise suppression requires a low inductance,
high frequency capacitor, whereas ripple suppression and proper
regulation require a large value capacitor. These capacitors are
most conveniently connected between the VDDP pin and GND1 pin,
and between the VISO pin and GNDISO pin. To suppress noise
and reduce ripple, a parallel combination of at least two capacitors

In applications involving high common-mode transients, ensure that
board coupling across the isolation barrier is minimized. Furthermore, design the board layout such that any coupling that does
occur equally affects all pins on a given component side. Failure
to ensure these steps can cause voltage differentials between pins,
exceeding the absolute maximum ratings specified in Table 15,
thereby leading to latch-up or permanent damage.
THERMAL ANALYSIS
The ADuM6020/ADuM6028 each consists of three internal die attached to a split lead frame. For thermal analysis, the die is treated
as a thermal unit, with the highest junction temperature reflected in

the θJA values, shown in Table 10 and Table 11. The value of θJA
is based on measurements taken with the devices mounted on a
JEDEC standard, 4-layer board with fine width traces and still air.
Under normal operating conditions, the ADuM6020/ADuM6028 can
operate at full load, but at temperatures greater than 85°C, derating
the output current may be needed, as shown in Figure 3 and Figure
4.
EMI CONSIDERATIONS
The ADuM6020/ADuM6028 dc-to-dc converters must, of necessity,
operate at a high frequency to allow efficient power transfer through
the small transformers. This high frequency operation creates high
frequency currents that can propagate in circuit board ground and
power planes, requiring proper power supply bypassing at the input
and output supply pins (see Figure 25 and Figure 26). Using proper
layout, bypassing techniques, and surface-mount ferrite beads in
series with the VISO and GNDISO pins, the dc-to-dc converters
are designed to provide regulated, isolated power that is below
CISPR22 Class B limits at full load on a 2-layer PCB with ferrites.
INSULATION LIFETIME
All insulation structures eventually break down when subjected to
voltage stress over a sufficiently long period. The rate of insulation
degradation is dependent on the characteristics of the voltage
waveform applied across the insulation, as well as on the materials
and material interfaces.
The two types of insulation degradation of primary interest are
breakdown along surfaces exposed to the air and insulation wear
out. Surface breakdown is the phenomenon of surface tracking
and the primary determinant of surface creepage requirements in
system level standards. Insulation wear out is the phenomenon
where charge injection or displacement currents inside the insulation material cause long-term insulation degradation.
Surface Tracking
Surface tracking is addressed in electrical safety standards by
setting a minimum surface creepage based on the working voltage,
the environmental conditions, and the properties of the insulation
material. Safety agencies perform characterization testing on the
surface insulation of components that allows the components to
be categorized in different material groups. Lower material group
ratings are more resistant to surface tracking and, therefore, can
provide adequate lifetime with smaller creepage. The minimum
creepage for a given working voltage and material group is in
each system level standard and is based on the total rms voltage
across the isolation, pollution degree, and material group. The
material group and creepage for the ADuM6020 and ADuM6028
are presented in Table 8 and Table 9.
Insulation Wear Out
The lifetime of insulation caused by wear out is determined by its
thickness, material properties, and the voltage stress applied. It
analog.com
is important to verify that the product lifetime is adequate at the
application working voltage. The working voltage supported by an
isolator for wear out may not be the same as the working voltage
supported for tracking. The working voltage applicable to tracking is
specified in most standards.
Testing and modeling show that the primary driver of long-term
degradation is displacement current in the polyimide insulation
causing incremental damage. The stress on the insulation can be
grouped into broad categories, such as dc stress, which causes
very little wear out because there is no displacement current, and
an ac component time varying voltage stress, which causes wear
out.
The ratings in certification documents are usually based on a 60 Hz
sinusoidal waveform because this stress reflects isolation from line
voltage. However, many practical applications have combinations
of 60 Hz ac and dc across the barrier as shown in Equation 1.
Because only the ac portion of the stress causes wear out, the
equation can be rearranged to solve for the ac rms voltage, as
shown in Equation 2. For insulation wear out with the polyimide
materials used in these products, the ac rms voltage determines the
product lifetime.
VRMS = VAC RMS2 + VDC2

VAC RMS = VRMS2 − VDC2
(2)
or
where:
VRMS is the total rms working voltage.
VAC RMS is the time varying portion of the working voltage.
VDC is the dc offset of the working voltage.
Calculation and Use of Parameters Example
The following example frequently arises in power conversion applications. Assume that the line voltage on one side of the isolation
is 240 V ac rms and a 400 V dc bus voltage is present on the
other side of the isolation barrier. The isolator material is polyimide.
To establish the critical voltages in determining the creepage, clearance, and lifetime of a device, see Figure 27 and the following
equations.

The working voltage across the barrier from Equation 1 is
Rev. C | 18 of 21
Data Sheet
ADuM6020/ADuM6028
APPLICATIONS INFORMATION
VRMS = VAC RMS2 + VDC2
VRMS = 2402 + 4002
VRMS = 466 V
This VRMS value is the working voltage used together with the
material group and pollution degree when looking up the creepage
required by a system standard.
To determine if the lifetime is adequate, obtain the time varying
portion of the working voltage. To obtain the ac rms voltage, use
Equation 2.
VAC RMS = VRMS2 − VDC2
VAC RMS = 4662 − 4002
VAC RMS = 240 V rms
In this case, the ac rms voltage is simply the line voltage of
240 V rms. This calculation is more relevant when the waveform
is not sinusoidal. The value is compared to the limits for working
voltage in Table 16 for the expected lifetime, which is less than
a 60 Hz sine wave, and it is well within the limit for a 50-year
service life.
Note that the dc working voltage limit is set by the creepage of
the package as specified in IEC 60664-1. This value can differ for
specific system level standards.
START-UP BEHAVIOR AND POWER
SEQUENCING
The start-up behavior of the isolated dc-to-dc converter is dependent on several external factors, including input voltage ramp rate,
source current capability, output voltage level, and output load
impedance. In general, the power-on sequence expects the output
voltage to be near 0 V and the input voltage to transition from
near 0 V to the rated operating voltage with a positive monotonic
characteristic.
When the external input voltage rises above the internal UVLO
voltage, the primary side of the dc-to-dc converter begins to turn on.
Because the output is not powered on at this point and therefore
not able to provide any feedback information, the regulator PWM
circuit is ramped in a linear fashion from 0% duty cycle toward
100% duty cycle, effectively ramping the output voltage from zero
to full open circuit voltage. This ramping is commonly referred to as
a slow start, a technique used in power conversion circuits where
insufficient information is available to the regulator to properly control the start-up process. This technique has the secondary benefit
of limiting the input transient (inrush) current caused by capacitive
loading.
to regulate the output voltage. The synchronization process takes
a finite amount of time, which results in the output voltage overshooting the programmed voltage. The amount of overshoot is
dependent on the load. At light loads, the overshoot tends to be
higher than at the rated load and generally does not exceed the
expected voltage by more than 10% to 20%. This behavior can be
observed in Figure 19 and Figure 20.
Several conditions can cause the start-up process to not proceed
as previously described, potentially resulting in excessive output
voltage overshoot. The two most common conditions to avoid are
multiple transitions of the input supply voltage above and below
the input UVLO threshold during the slow start time and the output
voltage starting above the secondary side UVLO point when the
turn-on process is initiated.
A nonmonotonic input voltage during turn-on can be caused by
several reasons. It can be an intentional, repeated turn-on and
turn-off of the input voltage or toggling of the PDIS pin, or it can
be due to insufficient input decoupling capacitance or high source
impedance, causing the input voltage to droop during the time the
output capacitance is being charged. The input current can be
much higher than the steady state operation during the turn-on of
the converter due to the load capacitance and must be considered
at the system level.
An output voltage higher than the secondary UVLO point during
turn-on can also be an issue. This issue is commonly caused by excessive output decoupling capacitance that is unable to discharge
below the UVLO point between power-down and power-up cycles.
This issue can also be caused by an output voltage being externally
forced during turn-on to be higher than the secondary UVLO point.
It is recommended that the output decoupling capacitance be kept
to ≤33 µF and to allow sufficient time for the output voltage to decay
to near zero before reapplying the input voltage.
If these operating conditions for proper turn-on cannot be met due
to system constraints or otherwise, it is recommended to observe
the output voltage during startup in the application for all operating
conditions. If voltage overshoot that exceeds approximately 6 V is
observed, it is recommended to add a 6.2 V Zener diode from VISO
to GNDISO.
As the output voltage rises, the secondary side UVLO threshold is
crossed, enabling the feedback circuits. When the output voltage
reaches its setpoint, 3.3 V or 5 V, the secondary side feedback
synchronizes with the primary side PWM and takes over control
